President Donald Trump's choice to run the Environmental Protection Agency says he does not believe global warming is the "greatest crisis."
Andrew Wheeler said at his Senate confirmation hearing Wednesday that while climate change is a "huge issue," it is something that needs to be addressed globally.
A report by the EPA and several other government agencies concluded last year that climate change is a man-made phenomenon that will cost the U.S. billions of dollars a year and lead to more wildfires, stronger hurricanes, and other weather-related calamities.
Wheeler, who has been acting EPA chief since July, said he has not read the report but that a staffer briefed him on it.
Massachusetts Democrat Ed Markey responded by saying Wheeler's policies easing federal regulations on fossil fuel emissions are the problem.
"You are a former coal industry lobbyist that is sitting here. That's the worst-case scenario, what you are proposing here. ... You are putting up a smokescreen to ensure there is an advancement of Donald Trump's dirty policies," Markey said.
